CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 351,315, dated October 19, 1886. Application filed September 2, IEEG. Serial No. 212,519. (No model.)

, of the invention, such as will enable others tical.

skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters or figures of reference marked thereon, which form a part of this specification.

Our invention relates to certain new and useful improvements in car-couplers; and it consists in the construction and combination of the parts, as will be hereinafter fully set forth, and specifically pointed out in the claims.

In the accompanying drawing, which illustrates our invention, we have shown the same by a longitudinal sectional view, in which A refers to the drawhead, which is attached to the car-body in the usual manner, and said draw-head is provided at its front portion with the usual bell-shaped opening or mouth, A, for the reception of the connecting-link. The draw-head is provided at its upper portion with a longitudinal slot or recess, within which the upper member, B, of the gravity-latch hook will lie, the upper edge thereof being on a line with the drawhead. The front portion of this member is provided with a downwardly-projecting portion, 1), the front edge of which is inclined, while the rear edge thereof is ver- At the extreme front end a recess, 0, is provided, which will rest upon the notched portion of the upper edge of the drawhead. The lower member, B, of the gravitylatch hook projects normally downwardly at an angle toward the front portion of the draw-head, and at its end itis provided with a weight, D. The rear portion of the gravity-latch hook adjacent to the portion where the members B and B are connected to each other is curved, so as to correspond with the vertical openingin the draw-head, to which they are connected by a transverse pin, (Z. The upper member, B, of

the draw-head is provided with an upwardlyprojeoting pin, 6, to which is attached a flexible connection or chain, E, which passes over a pulley, f, supported between the arms of a suitable bracket, F, which also forms a bearing for a vertical shaft, 9, which can be turned so as to wind thefiexible connection E thereon and elevate the gravity-latch hook when it is desired to release the coupling'link. The members B and B diverge from each other from their point of connection with the draw-head, and the gravity-latch is made of a single casting; or, in other words, all the parts thereof are integral with each other.

It will be obvious that when the couplinglink enters the draw-head it will abut against the front inclined portion of the latch-hook, so as to elevate the same and permit the coupling-link to pass under the head thereof, so as to engage with the inner vertical edge of said head. As soon as the coupling-link passes this vertical edge the latch will fall, so as to effectively couple the cars to each other.

The coupling hereinbefore described is extremely simple in construction and is effective in operation.

1. The combination, with a draw-head having a longitudinal slot, a recess, C, in its upper portion, and a vertical opening through which the gravity-latch passes, of a gravitylatch book which is pivoted to the draw-head at its rear portion and provided with members B and B, the upper member having a depending portion with an inclined front edge and a rear vertical edge, the lower member carrying at its free end a weight, D, substantially as shown, and for the purpose set forth.

2. In a car-coupling, the combination, with the draw-head A, having a longitudinal recess for the reception of the upper member of the gravity-latch hook, and an opening having its rear portion curved, of a gravity-latch hook having members B B, pivotally attached to the draw-head and provided with a curved portion at its rear end, and at the front end of the member B with a depending hook, the latch being secured to the draWhead, so that the major portion can slide under the car, substantially as shown.

In tcstimon y whereof we affix our signatures in presence of two witnesses.
